Systems

The first main system is the central nervous system which consists of the brain and the spinal cord. There are three main sections of the brain; the forebrain which contains the cerebrum and the parts of the diencephalon (the thalamus, hypothalamus, and epithalamus most importantly), the midbrain which is a part of the brain stem, and the hindbrain which consists of the medulla oblongata, the pons, and the cerebellum. The cerebrum, the picture on the right hemisphere of the model’s brain, is the…

The human heart contains a specialized conduction system through which it can create and transmit electrical impulses without any external neural input. The main components of the conduction system of the heart include the SA node, AV node, Bundle of His and the Purkinje fibers. The sinoatrial node (also known as SA node) is a natural pacemaker and is responsible for depolarization of the right and left atrium. This produces a P wave on the EKG reading which is normally 0.1 second and its normal…

appendicular skeleton consists of one hundred and twenty six bones that are part of the pectoral girdle, pelvic girdle, upper and lower limbs. Bones are connected to joints, ligaments, tendons and cartilage, which makes up the human skeletal system. The skeletal system has three major functions, which include, support, protection, and movement. Although all adults contain the same amount of bones in the body, males and females have a slight difference. Females have a wider pelvic region than…

wake up with the vibration from my smartphone alarm or the vibration from my Facebook messenger application notification. It was said that the neurons of the Somatic Nervous System carry information of the vibration from the external environment to the nervous system. By this, the information travels from the Central Nervous System to the effectors which can act on the external environment like striated muscles. In this case, the sensation of the vibration would then send neurons to my brain…
